INFLUENCE OF CURING TIME ON THE ANISOTROPIC MICROSTRUCTURE OF MAGNETORHEOLOGICAL ELASTOMER
Magnetoheological elastomer (MRE) is new kinds of smart materials whosedynamic mechanic performances can be controlled by an applied magnetic field.The MR effect of MRE is strongly influenced by the anisotropic microstructure ofmaterials.In this article,the influence of curing time on the anistropicmicrostructure was studied.Samples with different curing time were prepared.Their microstructures were observed and their dynamic shear modulus was alsomeasured.A critical curing time was found.When the curing time was shorter thanit,the regular column structure and MR effect was found increasing with the curingtime: when longer than it,the microstructure and MR effect of materials had a littlechange.To explain,the formation of microstructure of MRE was analyzed.
